Actinocenes is a group of metallocenes incorporating elements from the actinide series. An actinocene is a compound typically consisting of two cyclooctatetraenyl dianions (cot, which is C8H82−) bound to an actinide metal center (An) in the oxidation state IV, with the resulting general formula An(C8H8)2 The most studied actinocene is uranocene. The actinide-cyclooctatetraenyl bonding was shown by computational chemistry to be mainly due to mixing of actinide 6d orbitals into ligand pi orbitals and therefore donation of electronic charge to the actinide, with a smaller such interaction involving the actinide 5f orbitals. Other actinocenes include protactinocene (Pa(C8H8)2), thorocene (Th(C8H8)2), neptunocene (Np(C8H8)2), and plutonocene (Pu(C8H8)2). Octagonal sandwiched M(C8H8)2 exist for M = (Nd, Tb, Pu, Pa, Np, Th, U and Yb). 〔 ==See also== *Organoactinide chemistry 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Actinocenes」の詳細全文を読む スポンサード リンク
